For some reason whenever I want to make fun of the PS2's launch I always bring up Oni, but I guess that wasn't out at the very beginning, but it did seem like that was all everybody was playing back then, struggling to convince themselves that the game was any good in order to justify their purpose of buying the PS2 beyond getting a DVD player.
Eternal Ring is still really good and worth playing if you like From Software's games like King's Field and such, though.
Wow, Oni was so much better on the Mac. I don't even know why they released it on the PS2.
